How to create date picker that can be used within a fieldset.

How to create date picker that can be used within a fieldset.

Here is my java script.  I'm trying to figure out how to manipulate the code to create the functionality that i am looking for. I want to select the button for Monday and after clicking on it the correct date display for the button that is clicked

<script type="text/javascript">
      $(document).ready(function () {

          $("#date").datepicker();
          
      });

 </script>




Here is my html. 
<div style="float: left;"><b>Week One:</b>
   <fieldset data-role="controlgroup" data-type="horizontal" data-mini="true" /> 
        <input type="radio" name="week" class="twodate" id="radio-choice-a" value="Mon" checked="checked" onclick="radioclick()"/>
        <label for="radio-choice-a">Mon</label>
        <input type="radio" name="week" id="radio-choice-b" value="Tues" />
        <label for="radio-choice-b">Tues</label>
        <input type="radio" name="week" id="radio-choice-c" value="Wed" />
        <label for="radio-choice-c">Wed</label>
                        <input type="radio" name="week" id="radio-choice-d" value="Thurs" />
        <label for="radio-choice-d">Thurs</label>
        <input type="radio" name="week" id="radio-choice-e" value="Fri" />
        <label for="radio-choice-e">Fri</label>
                        
                </fieldset>

</div>
